Our official email policy states that email older than 90 days in the Inbox is moved to Deleted Items, not including subfolders of the Inbox. This wasn't a problem to implement in Exchange 2003. In 2010, however, it appears that Policy Tags applied to the Inbox also apply to its subfolders. How can I prevent this from occuring?

EDIT:

Here is the output of Get-RetentionPolicy:
